C Spire Wireless to offer iPhone 4S “in coming weeks”

C Spire Wireless has thrown in with the big boys, and begun taking pre-orders for the iPhone 4S. The private carrier – which covers the Memphis metropolitan area, Mississippi, Alabama, Florida Panhandle and Rome, Georgia – is yet to confirm pricing or availability for the fifth-gen handset, but will offer unlimited data among other things.

The announcement could be a sign that Apple is looking to continue broadening availability of the iPhone 4S within the US, a shift that began when Verizon offered the CDMA variant of the iPhone 4 back in February. In Europe, being able to pick and choose an iPhone from multiple carriers is common; meanwhile, in the US, Apple will begin offering a SIM-free and unlocked version of the 4S sometime in November.
